The partner will typically have to put in the airline code for the program you're using which is 'SK' in the systems of virtually every *A partner. You need to then include your EBX and your number, it really doesn't matter whether you use EBB/EBS/EBG/EBD since the system will pull your status and uses whatever it gets in return. There is no *A partner anymore that deducts status from your input.

So SK and EBD123456789 are the usual inputs.
